Be it known that 1, THOMAS E; Bnoonaa .citizen of the United States,residing at provement in silos, and particularly to asilo built up ofindependent sections or i,

` staves, preferably ofv vconcrete or the like,

interfitting.

and peculiarly constructed to provide for The main object of theinvention is the construction of a silo in which the staves for 'thegreater portion of the wall are constructed to provide complementaryribs and recesses for the interiitting connection of such staves', thesimilar sections adjacent and forming the door openings in the silobeing formed for interfltting with the main 'staves, and also formed ontheir proximate `edges to receive and support sill blocks, and

' Yeo `to receive and support the doors. i at A. still further object isto 'form the staves so as to vinterit with each other for Aa portion'oftheir length only and to be spaced from each other .for the greater.portion of their length. i e;

The invention in the preferred details of construction, will bedescribed in the follow- .-ing specification, reference being-had particularly to the accompanying drawings, in

constructed in accordance with my invention.v Fig. 2 is a perspectiveview of one of the main 'staves Fig. 3 is a perspective view of one Aofthe door opening staves.v Fig. 4 is a similar view of the opposing dooropening staves. Fig. 5 is a perspective view of one The slabs orstavesmaking up the silo are of four distinct types,4 the main staves,constituting .those making up the greater portion of the wall,- thedooropening stave's, of dierent 'types on opposite sides ofthe door.opening, vand the sill blocks for supporting the doors. All thedifferent types 0f tPatcntedDec.-29,191d

stares and blocks are peculiarly constructed for interitting, and are ofappropriate curvature transversely to properly intert to ed complete theoutline shape of the silo.

The main staves 1, shown in Fig. 2, are concrete blocks of appropriatelength and thickness formed on one edge with a longitudinally extendingrecess 2, and on'the op- 65 posite edge at 'the ends thereof with shortlongitudinally extending complementaryl projections or. ribs 3, whichextend beyond a similarly formed rib 3 intermediate said short ribs. v

The door opening staves, illustrated frespectively in Figs. 3 and4,'comprise block like slabs and, v-similarin general size and shape tothemain staves 1.. The'stave 5 is formed on its relatively outer"longi-i 75 tudinal edge with ribs 7, corresponding to the ribs 3 ofthemain stave, andv on its relatively inner longitudinal edge with achannel 9,terminatingl short of the respective ends of the stave. Thechannel 9 has its respective Walls 10 and 11 at right angles toeachother, andin parallelism with the side edge and inner surface of'the stave re spectively, said channel being located at the juncture ofthe'side edge and inner lsurface of the stave.

That edge of the stave formed with a channel'9` is also formed above theupper end of the channel with a groove 12,

corresponding in size and yshape to the groove 2 of the main4 stave, andbelow the lower end of the channel 9 with another groove 13 alined .withandv corresponding to the groove 12. The remaining door stave 6 isformed in its relatively outer longitudinal edge with a-channel 14corresponding to the channel 2 of the main stave, and is cut awayv onits relatively inner longitudinal edge to present a block likeprojection corresponding in length to that of the channel 9 of the stave5. The block like projection coincides with the outer face of the stave,and is of less width than the` stave, presenting edge shoulder 16adjacent the inner 'face of the stave,"A as shown in Fig.` 4. ATherelatively inner edge of the block .6 isformed above and below theprojection ldwth centrally arranged alined ribsy 17 l 8. v' y The sillblocks which are approximately y of the same widt'nof the staves but ofmate- 1 it..

and relation in an obvious manner, the ribs 3 of one fitting into thegrooves or recesses 2 of the other. The door opening slabs are similarlyconnected to the adjacent main slabs, being arranged in spaced relationto form door openings. The upper and lower ends of the door openingslabs of eachhorizontal section of the silo, are connected by the sillblocks, the grooves 20 of which cooperate with-the ribs 17 and 18 of the1mmediately adjacent endwise meeting similar door opening slabs '6, theribs 21' of the sill blocks cooperating with the recesses 12 and 13 ofthe endwise meeting adjacent similar door opening slabs 5, all asclearly shown in Fig. 6. The door opening slabsof the re spectivesuperimposed section of the silo 'are thus interlocked. As thusconnected the channels 9 of the door opening "slabs 5 and the shouldersof the door opening slabs 6, between the respective sill blocks providebearing portions for doors 22, which doors vare preferably constructedof cross strips secured by longitudinal cleats 23. The channels 9 andshoulders 16 are preferably of such depth that the inner surface of thedoors are flush with the inner surface of the staves. Metallic bands24'encircle the meeting ends of the staves, being tightened to securethem in practically rigid relation. The meetingends of the main stavesare preferably arranged in offset relation transversely of the silo, sothat each stave interlocks with two adjacent staves at the meeting endsto secure a more rigid structure.

lVith the staves assembled insilo forming relation it will be notedvthatthe ribs 3 of the-main staves engage the grooves only of adjacent stavesfor a portion of their length, and that the ribs 3 on thenarrowerportion of the staves does not come -in Contact4 with theadjacent staves, thus equal stress on those.

" 4ing of the slabs or staves at spacing the greater portion of thelongitudinal .edges 4 of adjacent staves from each other. Thereinforcing bands 24 cover the 'meeting edges of the staves, aindas the.staves are not subjected to any strain or unportions not covered by thebands due to their spaced relation, the difliculty heretofore met within building silos of concrete slabs'due to the breakpoints not protectedthe bands in the act of tightening the bands is overcome in a mosteffective manner. After the bands are properly tightened, the spaces oropenings between the staves are filled with a sealing medium, asconcrete, thus insuring an absolute tight connection therebetween.

. The silo may be constructed of as many sections as desired and isprovided with the usual roof 25, which may be of wood or of -any desiredmaterial.

Having thus described my invention what I claim is 1. A silo constructedof composite` staves, one of said staves being formed on its meetingedges with a channel of uniform depth, the meeting edge of the adjacentstave bcing formed with a rib to iit in said channel, an intermediateportionv of the stave edge carrying said rib being cut away for its fullwidth including the rib whereby to provide a rib having end portions offull dimension and an intermediate portion of less dimension.

2. A composite stave for silos formed on one edge with a channel ofuniform depth, the opposing edge of the stave having its intermediateportion cut-away throughout its full width' to formy a recess in saidedge, the portions of said edge of the stave above and below the recessbeing formed with ribs corresponding in size to that of the channel andeach wall of the Yrecess being formed with a rib in alinement with theiirst mentioned ribs but of less sectional dimension than the latter.

3. A silo constructed of composite staves, the door opening edge of oneof said staves being formed with a channel adjacent each end thereof andan angular recess in the juncture of said` edge with the face of thestave, said recess extending throughout the length of the stave betweenthe adjacent ends of the channels, the door opening edge of the opposingstave being formed adjacent 'each end with ribs lcorresponding in sizeand shape to said channels, and intermediate said ribs with a projectionof less width than the edge of the full length between adjacent ends ofthe ribs.

4. A silo constructed of composite staves, the door opening edge of oneof said staves being formed with a channel adjacent each end thereof andan angular recess in the juncture of said edge with the face of thestave, said recess extending throughout the' length of the stave betweenthe adjacent ends of the channels, the door opening edge of the opposingstave being formed adjacent each end with ribs corresponding in size andshape to said channels, and intermediate said ribs with a projection ofless width than the edge of the full length bctween adjacent ends of theribs, said projection havingone edge flush with one face of the stave topresent an angular recess stave, said recess extending throughout thelength of the stave between the adjacent ends of the channels, the dooropening edge of the opposing stave being formed adjacent each end withribs corresponding in size and shape to said channels, and intermediatesaid ribs with a projection of less Width than the edge of the fulllength between adjacent ends of the ribs, said projection having oneedge flush with one 'face ofl the stave to present an angular recessadjacent the opposing face of the stave, and sill blocks formed onopposing edges with ribs and projections to coperate With the channelsand ribs of the door opening edges of THOMAS E.
